The main vibrating component of the device is the fuselage 5. At the same time, the fuselage 5 is supported and shaken by the buffer device 3 and the rotating device 2, which makes the buffer device 3 and the rotating device 2 easy to be damaged. By sliding the second protective frames 9 on both sides, the buffer device 3 on the left and the buffer device 3 on the right can be effectively repaired. At the same time, unfolding the second protective frame 9 during work can also prevent external dust and other impurities from entering and affecting the operation of the device.

[0056] In this embodiment, the sizes of the first protective frame 6 and the second protective frame 9 are both much larger than the vibration range of the fuselage 5 , and the first protective frame 6 and the second protective frame 9 both surround the fuselage 5 .

[0057] It should be noted that when the second protective frame 9 is fully unfolded and the connecting plate 7 is removed, it should be ensured that the screen and other large components inside the fuselage 5 can be effectively taken out and repaired.

[0058] In this embodiment, the fixing box 1001 is fixedly installed on the upper end of the base 1, the adjusting nut 1003 is located outside the fixing box 1001 and has a circle of anti-slip strips on the outer surface, and every two adjacent second fixing components 10 are mirror-symmetrical about the base 1.

[0059] It should be noted that by rotating the adjusting nut 1003, the second protective frame 9 can be quickly fixed and loosened to achieve the movement adjustment of the second protective frame 9 and facilitate the maintenance of the easily damaged parts on the left and right sides of the device.

[0060] To sum up: the multifunctional protective component supports and installs the dustproof cloth 11 through the second protective frame 9 and the first protective frame 6, and provides dustproof protection for the environmentally friendly planar reversing screen. At the same time, the roller 903 on the second protective frame 9 is designed so that the protective component can slide left and right on the base 1, which is not only convenient for inspection and maintenance of the left and right ends of the equipment, but also does not affect the loading and unloading of the equipment. At the same time, the first fixed component 8 and the detachable connecting plate 7 are convenient for the overall inspection of the device, including large parts inside the fuselage 5 such as screens and partitions; what is special is that the first fixed component 8 uses the first spring 804 to plug and fix the fixed sheath 803 and the connecting plate 7 to ensure the stability of the fixation.

[0061] The environmentally friendly planar reversing screen, through the design of the second fixing component 10, can achieve a stable connection between the second protective frame 9 and the base 1 of the environmentally friendly planar reversing screen, avoiding loosening and displacement during vibration, which causes the dustproof cloth 11 to loosen, thereby affecting the effect of the protective component; what is special is that the second fixing component 10 ensures the stability of the fixing claw 1002 to the second protective frame 9 through the second spring 1004, and at the same time, the tightness of the second fixing component 10 can be controlled by rotating the adjusting nut 1003, which is convenient for controlling and adjusting the second protective frame 9, thereby facilitating the maintenance of the device.

[0062] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
